HORRIBLE EXPERIENCE!!!!!

Horrible experience. I have made a payment of R115 yesterday for my decoder which I was supposed to pay today...but my channels are still blocked. When I called they said I have been charged R7.00 subscription fee which I don't even know what for because I only use my decoder. So I got a call from them telling me that I am subscribed for online streaming, when I tell them that I don't even know what that is they insist i must pay. And I can't pay for something I don't even know?. In May they told me that I have two accounts on my account and I told them that I don't know anything about that then they said they will take out that "online streaming " thing of theirs. But now they are still harassing me because on top of the R115 I have payed yesterday I paid an additional R10 today yet my decoder is still blocked. My reference number is ***. Please help me resolve this
